Universal Fit. Every ball kit includes 5 bolts to allow fitment to any bike and eliminate unsightly adapters.

Larger size. Our ball is 1.125”, and even that small increase in diameter makes a big difference in rigidity. This means you don’t have to overtighten the arm to keep it from moving while riding.

Won’t Crush. Our aluminum-filled base ball, coated with high-quality nitrile rubber won’t degrade under extended compression. You won’t have to repeatedly adjust your mirrors, because both ends of the system are designed to last.

Won’t spin. We include a lock washer that secures the ball in relation to the bike.
